Application filed March 22, 1897. Serial No. 628,790. (No model.)

To aZZ whom it may concern:

Be it known that we, MERRITT TAOITUS WALLACE, of New Lexington, andALEXAN- DER I-I. REYNOLDS, of MoXahala, Perry county, Ohio, citizens ofthe United States, have invented certain new and useful Improvements inNut-Locks; and we do hereby declare the following to be a. full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in nut-locks, and has" for itsobject the construction of means whereby the unscrewing or working ofthe nut off of its bolt due to the jar and vibration incident to usewill be prevented in a simple and inexpensive manner.

We accomplish the objects of the invention by means of the mechanismillustrated in the accompanying drawings, in which- Figure l is a viewin side elevation of our improved nut-lock, showing its application tonuts used in railroad-rail joints, the View showing parts of a rail andfish-plate and showing one nut in place and locked and a bolt without.the nut, but with the lock in positionon the bolts; Fig. 2, a detail inhorizontal section of the railroad-rail and one of the fish-platesandshowing the bolts andnutlock in plan view. One of the nuts is screwedinto place and locked and the other nut is on of the bolt.

Similar letters of reference indicate like parts throughout both viewsof the drawings.

A represents a railroad-rail; B, the fishplate to connect the abuttingends of the rails; O, the bolts which pass transversely through therails and the fish-plates on each side of the rails, and D the nutswhich screw onto the threaded'ends of the bolts, all of which parts areand may be of any usual construction.

Our nut-lock consists of the body part E, having on its ends the loopsE, which stand out laterally and in opposite directions from thebody-part E. The material from which the lock is made will preferably bewire of suitable diameter, depending on the size of the nuts to be heldand the strain to be resisted, and the ends of the wire after leavingaround the projecting. end of the bolt.

the loops will occupy a return position alongside of the body E untilafter the nuts are screwed down into place. The openings in the loopswill be large enough to allow a bolt to be projected through the saidopening in the manner as clearly shown in the drawings. The nut-lock ismade to connect two bolts and is placed in position on the bolts beforethe nuts are screwed onto same. I In order that the surface under thenut may be as near level as possible and thereby afford a good seat forthe nut, the wire will be flattened, as shown, and the wire used willconsequently be large enough in diameter to permit of this flattening.

After the nuts are screwed down firmly into place the end G nearest toeach of the nuts will be bent upwardly against the side of the nut andthen over the top of the nut find 1g. 1 shows an end bent over one ofthe nuts in the manner ust described, the position before the bend wasmade being shown by the dotted lines.

When one of the ends of the wire is bent around a nut, as abovedescribed, it makes a positive bar or stop for the nut, which no amountof jarring or wrenching on either the bolt 0r nut can change untiltheend is bent back into the position which it had when the nut wasscrewed on. r 7

We have shown the nut-lock as applied to a rail-joint because it isparticularly well adapted to that use, but we do not wish to limit theapplication of the device to use on rail-joints, nor to any specifiedadaptation of same; but

What we do claim as new, and wish to secure by Letters Patent of theUnited States, is-

1. A nut-lock made out of a wire rod and comprising a straight barforming a body portion, lateral loops formed by making a returnbend atboth ends of the body portion, then bending the ends outwardly andapproximately in a circular direction to intersection at the first bend,and after the bolt and nut are in position, bending the ends upalongside of and thence across the top of the nut, substantially asdescribed and specified.
